Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to an assembled steel pipe pile cap and a steel pipe pile combined structure. Background Art

[0002] In the construction of large-scale infrastructure such as bridges, ports, and docks, piers are crucial connecting structures. Their stability and construction efficiency are crucial to the progress and quality of the entire project. Piers are typically supported by multiple steel pipe piles, the tops of which are connected to load-bearing beams through pile caps to ensure the stability of the entire pier structure.

[0003] During the traditional construction of steel pipe pile caps for piers, construction workers typically need to dig a hole in the pile cap that matches the diameter of the steel pipe pile in order to insert the pile. However, this step not only requires precise cutting of the pile cap, but also requires extensive welding between the steel pipe pile and the pile cap to ensure a secure connection between the two.

[0004] This traditional construction method has numerous drawbacks. First, cutting and welding operations are not only time-consuming and labor-intensive, but also often difficult to maintain in precision, compromising the stability and safety of the entire trestle structure. Second, the sparks and fumes generated during the cutting and welding process pose a threat to the construction site environment and worker health. Furthermore, with increasingly stringent environmental protection requirements, this energy-intensive and highly polluting construction process is increasingly unable to meet the demands of modern engineering construction. Utility Model Content

[0005] In view of the shortcomings of the prior art described above, the technical problem to be solved by the present invention is to provide an assembled steel pipe pile cap and a steel pipe pile assembly structure, which is used to solve the technical problems that exist in the construction process of existing trestle steel pipe pile caps, such as the need for a lot of time and labor for cutting and welding operations, and low installation efficiency.

[0006] To achieve the above-mentioned purpose, the utility model provides an assembled steel pipe pile cap for connecting a steel pipe pile and a load-bearing beam, comprising: a pile cap body and a limiting member arranged on the pile cap body; the pile cap body comprises an internally penetrating sleeve and an end plate arranged on the top of the sleeve, and the end plate is used to install the load-bearing beam; the limiting member is arranged on the end plate; wherein the sleeve is sleeved on the top of the steel pipe pile; the limiting member comprises a limiting plate and a locking structure arranged on one side of the limiting plate, the limiting member is locked with the end plate through the locking structure, and at the same time the limiting plate presses the load-bearing beam onto the end plate.

[0007] As a more preferred embodiment, the stopper also includes a groove structure provided on the other side of the stopper plate and adapted to the load-bearing beam, with the notch of the groove structure facing the lower flange of the load-bearing beam. The stopper plate and the end plate are locked together by the locking structure, while the load-bearing beam is simultaneously pressed against the end plate by the groove structure. Thus, the groove structure and the locking structure achieve a quick connection between the steel pipe pile and the load-bearing beam.

[0008] As a more preferred embodiment, the limiting member includes a plurality of limiting plates, each of which is spaced apart on the end plate and located on either side of the load-bearing beam. Each limiting plate presses the load-bearing beam against the end plate via a locking structure on one side and a groove structure on the other side. Thus, the multiple limiting plates and the locking and groove structures on both sides further enhance the secure connection between the steel pipe pile and the load-bearing beam.

[0009] As a more preferred embodiment, the locking structure includes a bolt and a nut, wherein the bolt passes through one side of the limit plate and is connected to the nut. In this way, the connection flexibility and detachability are improved by locking with the bolt and nut, and the amount of cutting and welding work is significantly reduced.

[0010] As a more preferred method, one side of the limit plate is provided with a through hole, through which the bolt passes to connect with the nut. In this way, the load-bearing beam is pressed onto the end plate through the bolt, nut, and groove structure, simplifying the structure of the assembled steel pipe pile cap and avoiding cumbersome and time-consuming steps.

[0011] As a more preferred embodiment, the pile cap body further includes a corbel plate, which is disposed on the outer peripheral wall of the sleeve and abuts the end plate. Thus, the corbel plate abuts the end plate at the top of the sleeve, forming a more stable connection structure that can effectively distribute and resist the load from the load-bearing beam, ensuring the stability of the entire structure.

[0012] As a more preferred embodiment, the symmetry center of the end plate coincides with the center of the sleeve, which facilitates installation and positioning during construction and ensures that the load transferred from the load-bearing beam through the end plate is evenly distributed to the sleeve and the steel pipe piles connected thereto.

[0013] The utility model also provides a steel pipe pile assembly structure, comprising: a steel pipe pile; and the assembled steel pipe pile cap as described above, wherein a sleeve of the assembled steel pipe pile cap is sleeved on the top of the steel pipe pile.

[0014] As a more preferred embodiment, the length of the sleeve is shorter than the length of the steel pipe pile, which facilitates the processing of the assembled steel pipe pile cap and reduces the weight and difficulty of the lifting operation.

[0015] As a more preferred embodiment, the inner diameter of the sleeve is larger than the outer diameter of the steel pipe pile, so that the assembled steel pipe pile cap can be sleeved on the top of the steel pipe pile.

[0016] As described above, the assembled steel pipe pile cap and steel pipe pile assembly structure of the present invention have the following beneficial effects:

[0017] The assembled steel pipe pile cap of the utility model is that after the steel pipe pile is driven to the designed elevation, the sleeve is sleeved on the top of the steel pipe pile, and the limiting piece arranged on the end plate is locked with the end plate through the locking structure. At the same time, the limiting plate presses the load-bearing beam onto the end plate, thereby realizing a fast and firm connection between the steel pipe pile and the load-bearing beam, improving the stability and safety of the entire trestle structure, saving installation time, improving installation efficiency, and improving the flexibility and disassembly of the connection, and greatly reducing cutting and welding operations, simplifying the construction process, reducing construction difficulty and cost, and improving construction safety and environmental protection.

[0018] The steel pipe pile assembly structure of the present invention features an assembled steel pipe pile cap that is tightly connected to the steel pipe pile via a sleeve, forming a stable overall structure that enhances the structure's vertical load-bearing capacity and lateral force resistance. The assembled steel pipe pile cap helps disperse and resist the load from the load-bearing beam, preventing deformation or damage to the structure due to uneven loads, thereby improving the stability of the overall structure. The assembled steel pipe pile cap connects the steel pipe pile to the load-bearing beam, reducing cutting and welding work at the construction site, lowering safety risks such as fire and explosion, and providing a safer working environment for construction personnel.

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the invention.

[0043] like Figure 1-4 As shown, the utility model provides an assembled steel pipe pile cap for connecting a steel pipe pile 3 and a load-bearing beam 4, comprising: a pile cap body 1 and a limiting member 2 arranged on the pile cap body 1; the pile cap body 1 comprises an internally penetrating sleeve 11 and an end plate 12 arranged on the top of the sleeve 11, and the end plate 12 is used to install the load-bearing beam 4; the limiting member 2 is arranged on the end plate 12; wherein, the sleeve 11 is sleeved on the top of the steel pipe pile 3; the limiting member 2 comprises a limiting plate 21 and a locking structure 22 arranged on one side of the limiting plate 21, the limiting member 2 is locked with the end plate 12 by the locking structure 22, and at the same time, the limiting plate 21 presses the load-bearing beam 4 onto the end plate 12.

[0044] The assembled steel pipe pile cap of the present invention is that after the steel pipe pile 3 is driven to the designed elevation, the sleeve 11 is sleeved on the top of the steel pipe pile 3, and the limiting piece 2 provided on the end plate 12 is locked with the end plate 12 by the locking structure 22. At the same time, the limiting plate 21 presses the load-bearing beam 4 onto the end plate 12, thereby realizing a fast and firm connection between the steel pipe pile 3 and the load-bearing beam 4, improving the stability and safety of the entire trestle structure, saving installation time, improving installation efficiency, and improving the flexibility and disassembly of the connection, and greatly reducing cutting and welding operations, simplifying the construction process, reducing construction difficulty and cost, and improving construction safety and environmental protection.

[0045] In this embodiment, if Figure 1-3 As shown, the limiting member 2 further includes a groove structure provided on the other side of the limiting plate 21 and adapted to the load-bearing beam 4. The notch of the groove structure faces the lower flange 42 of the load-bearing beam 4. The limiting plate 21 is locked to the end plate 12 by the locking structure 22, and the load-bearing beam 4 is pressed against the end plate 12 by the groove structure. The groove structure and the locking structure achieve a quick connection between the steel pipe pile and the I-beam.

[0046] In this embodiment, if Figure 2 As shown, the groove structure includes a slot, the slot opening of which faces the lower flange 42 of the load-bearing beam 4, and the inner contour of the slot matches the shape of the lower flange 42 of the load-bearing beam 4. The load-bearing beam 4 includes an I-beam, which is primarily composed of an upper flange 41, a lower flange 42, and a web 43 connecting the upper and lower flanges 41, 42. The flange portion above the I-beam is referred to as the upper flange 41, and the flange portion below the I-beam is referred to as the lower flange 42. After the sleeve 11 is sleeved on the top of the steel pipe pile 3, the I-beam is placed on the end plate 12, the lower flange 42 of the I-beam is clamped in the clamping groove, and the limiting plate 21 and the end plate 12 are locked by the locking structure 22 to press the I-beam onto the end plate 12, thereby realizing the connection between the steel pipe pile 3 and the I-beam, thereby greatly reducing cutting and welding operations, simplifying the construction process, and improving installation efficiency.

[0047] In this embodiment, if Figure 1-3As shown, the limiting member 2 includes a plurality of limiting plates 21, each of which is spaced apart on the end plate 12 and located on either side of the load-bearing beam 4. Each limiting plate 21 presses the load-bearing beam 4 onto the end plate 12 via a locking structure 22 on one side and a groove structure on the other side. Thus, the multiple limiting plates 21, along with the locking structures 22 and groove structures on both sides, further enhance the secure connection between the steel pipe piles 3 and the I-beam, thereby improving the stability and safety of the trestle structure.

[0048] In this embodiment, if Figure 3 As shown, there are four limit plates 21, each of which is spaced apart on the end plate 12 and symmetrically arranged on both sides of the load-bearing beam 4. The four limit plates 21 are only one embodiment of the present invention and are not intended to limit the present invention.

[0049] In this embodiment, if Figure 1-2 As shown, the locking structure 22 includes a bolt 221 and a nut 222. The bolt 221 passes through one side of the limit plate 21 and is connected to the nut 222. A through hole is provided on one side of the limit plate 21, through which the bolt 221 passes and is connected to the nut 222. The bolt 221, nut 222, and groove structure are used to press the load-bearing beam 4 onto the end plate 12, simplifying the structure of the prefabricated steel pipe pile cap, avoiding cumbersome and time-consuming steps, and significantly reducing the amount of cutting and welding work. Furthermore, the locking mechanism of the bolt 221 and nut 222 improves the flexibility and removability of the connection.

[0050] In this embodiment, if Figure 1-3 As shown, the pile cap body 1 further includes a corbel plate 13, which is disposed on the outer peripheral wall of the sleeve 11 and abuts against the end plate 12. The corbel plate 13 abuts against the end plate 12 at the top of the sleeve 11, forming a more stable connection structure that can effectively distribute and resist the load from the load-bearing beam 4, thereby ensuring the stability of the entire structure.

[0051] In this embodiment, if Figure 1-3 As shown, the end plate 12 is square in shape, and the corbel plates 13 are respectively provided at both ends of the end plate 12. The corbel plates 13 at both ends of the end plate 12 are centrally symmetrically arranged along the center of the sleeve 11, ensuring the force balance of the steel pipe pile 3 and ensuring stability and safety during the construction process.

[0052] In this embodiment, if Figure 1-3As shown, the symmetry center of the end plate 12 coincides with the center of the sleeve 11, which facilitates installation and positioning during construction and ensures that the load transmitted by the load-bearing beam 4 through the end plate 12 can be evenly distributed to the sleeve 11 and the steel pipe pile 3 connected thereto. This balanced stress state helps to reduce stress concentration in the structure and improve the stability and durability of the overall structure.

[0053] like Figure 4 As shown, the present invention further provides a steel pipe pile assembly structure, comprising: a steel pipe pile 3; and the assembled steel pipe pile cap as described above, wherein the sleeve 11 of the assembled steel pipe pile cap is sleeved on the top of the steel pipe pile 3.

[0054] In the steel pipe pile combination structure of the present invention, the prefabricated steel pipe pile cap is tightly connected to the steel pipe pile 3 via a sleeve 11, forming a stable overall structure and enhancing the structure's vertical bearing capacity and lateral force resistance. The prefabricated steel pipe pile cap helps to disperse and resist the load from the load-bearing beam 4, preventing the structure from deformation or damage due to uneven force, thereby improving the stability of the overall structure. The prefabricated steel pipe pile cap connects the steel pipe pile 3 to the load-bearing beam 4, reducing cutting and welding operations at the construction site, reducing safety risks such as fire and explosion, and providing a safer working environment for construction personnel.

[0055] In this embodiment, if Figure 4 As shown, the length of the sleeve 11 is smaller than that of the steel pipe pile 3 , which facilitates the processing of the assembled steel pipe pile cap and reduces the weight and difficulty of the hoisting operation.

[0056] In this embodiment, if Figure 4 As shown, the inner diameter of the sleeve 11 is larger than the outer diameter of the steel pipe pile 3 , so that the assembled steel pipe pile cap can be sleeved on the top of the steel pipe pile 3 .

[0057] In summary, the assembled steel pipe pile cap and steel pipe pile combination structure of the present invention, after the steel pipe pile 3 is driven to the designed elevation, the sleeve 11 of the assembled steel pipe pile cap is sleeved on the top of the steel pipe pile 3, forming a stable overall structure, and the limiting plate 21 is locked with the end plate 12 by the locking structure 22, while the limiting plate 21 presses the load-bearing beam 4 onto the end plate 12, thereby achieving a fast and firm connection between the steel pipe pile 3 and the load-bearing beam 4, reducing the cutting and welding operations at the construction site, improving installation efficiency, simplifying the construction process, reducing construction difficulty and cost, and improving construction safety and environmental protection. Therefore, the present invention effectively overcomes the various shortcomings of the existing technology and has a high industrial utilization value.
